What This IB ACIO Grade II Mock Test Covers: Section by Section
Each question in this mock test comes from one of the 5 sections that Intelligence Bureau tests in the actual Tier 1 CBT. Below is exactly what you will practice per section.
Current Affairs: 20 Questions
Current Affairs questions test national and international events from the 6 to 12 months before the actual exam date. In particular, high frequency topics include: government schemes such as Ayushman Bharat and Jal Jeevan Mission, international summits like G20, awards such as Padma Vibhushan and Nobel Prize, ISRO space missions, Cabinet appointments, and major sports results from ICC cricket, the Olympics, and the Asian Games.
General Studies: 20 Questions
General Studies tests Class 10 level knowledge across Indian history, polity, geography, economics, and general science. In particular, polity and history together account for 10 to 12 questions in most IB ACIO papers. Key focus areas include constitutional provisions such as Fundamental Rights and Directive Principles, the freedom movement from 1857 to 1947, river systems, GDP basics, and human organ systems.
Numerical Aptitude: 20 Questions
Numerical Aptitude tests arithmetic and data interpretation at Class 10 mathematics level. In fact, data interpretation using bar graphs, pie charts, and mixed tables alone carries 5 to 8 questions per paper. Other high frequency topics include percentage, profit and loss, simple and compound interest, ratio, time and work, and HCF and LCM.
Reasoning and Logical Aptitude: 20 Questions
Reasoning tests verbal reasoning, non verbal reasoning, and logical deduction across 20 questions. Specifically, verbal topics cover analogy, coding decoding, and blood relations. Non verbal topics include pattern recognition and mirror images. Logical topics test syllogisms and statements with assumptions or conclusions.
English Language: 20 Questions
English Language is the fastest section in IB ACIO Tier 1 with a recommended attempt time of only 8 minutes. Indeed, candidates who read English newspapers daily for 30 days before the exam consistently score higher here. Tested topics include grammar rules, synonyms and antonyms, reading comprehension passages, and sentence error detection.
IB ACIO Grade II Negative Marking: How Scoring Works in Tier 1
4 wrong answers cancel exactly 1 correct answer under the IB ACIO 0.25 negative marking rule. So, use this confidence framework on every question during your mock test:
- Above 70 percent confidence: Attempt without hesitation; expected score value stays positive
- Between 50 and 70 percent after eliminating 2 options: Attempt with calculated risk; elimination improves your odds measurably
- Below 50 percent confidence: Skip the question; expected value from guessing turns negative under the 0.25 rule
- Unattempted questions: Score zero with no penalty attached; skipping never costs marks
Accuracy vs Attempt Rate: Net Score Comparison
Accuracy improves your IB ACIO Grade II net score more than answering additional questions when negative marking is active. For instance, the difference between 75 percent and 85 percent accuracy on the same 85 questions is 10.7 marks.
| Questions Attempted | Accuracy | Correct | Wrong | Net Score |
|---|---|---|---|---|
| 85 | 75% | 63.75 | 21.25 | 58.4 marks |
| 85 | 85% | 72.25 | 12.75 | 69.1 marks |
| 90 | 80% | 72 | 18 | 67.5 marks |
| 90 | 88% | 79.2 | 10.8 | 76.5 marks |
So, build accuracy first in practice sessions, then increase your attempt count per mock test.
IB ACIO Grade II Tier 1 Cut Off: Score to Target in Every Mock Test

In fact, general category cut offs typically range between 62 and 72 marks per recruitment cycle.

| Numerical Aptitude | 16 minutes | 5th | Hard cap at 16 minutes regardless of difficulty |
IB ACIO Grade II Selection Process: Where Tier 1 Fits
